This robust aftermarket water pump case insert liner serves as a trustworthy drop‑in replacement for Tohatsu 40‑90HP marine outboard boat motors. It matches OEM part numbers 3B7‑65011‑0, 3B7‑65238‑0, 3B7650110 and 3B7652380.
It is built with precision base metal covered by premium chrome plating. This case insert delivers solid wear resistance, stable anti‑aging traits, and reliable salt‑water corrosion resistance for extended marine service.
It creates a smooth contact surface for the rotating water pump impeller. It also cuts down inner‑wall abrasion when cooling components keep running under demanding on‑water operating conditions.
This insert gets precision‑machined following original OEM dimensions, so it maintains consistent inner‑surface geometry amid ongoing impeller friction. It resolves common cooling‑system troubles, such as liner scoring, early impeller wear and insufficient cooling‑water flow.
All key dimensions meet OEM requirements. You can complete quick, straightforward drop‑in installation, and no trimming or extra adjustments are needed. Remember to thoroughly wipe down contact surfaces inside the water pump housing bore before mounting. Take extra care not to nick the polished chrome surface throughout assembly.
Swap your scored, worn or deformed factory water pump case insert with this component, and you will bring back stable water‑pump performance for your Tohatsu outboard. Stick to routine marine maintenance schedules. These practices will help extend cooling‑system service life and keep consistent engine cooling out on the water.
